Top 10 strangest genetic links in humans

Yesiiii, we know: we share 98% of our DNA with chimpanzees. We’ve been told it, repeated it, and it no longer surprises anyone (even if in real life, it’s completely crazy). On the other hand, there are other things around us that have more (much more) genes similar to ours than we thought! What ? Didn’t know about the banana? Bahahaha bunch of truffles.

1. Sea anemones

Our common point: the louse-iv gene.

This is the latest big scientific discovery in terms of genetic similarities with humans! According to a team of international researchers, the starry sea anemone has this gene on its tentacles. On our side, we find it in the development of hearing. Thanks to their filamentous structure, these cells can detect mechanical stimuli. Results: the human detects the sound vibrations, the anemone detects the movements. Crazy, right?

2. The Abyssinian domestic cat (90%)

Which means… Yes, cats share more DNA with us than dogs (84%), cows (80%) or mice (75%). Afterwards, come to think of it… Eating and sleeping are the two things that make me really happy, so in the end it’s not that bad.

3. Dolphins (98.5%)

98.5% similarity. Geneticists have discovered that the human genome and that of dolphins are fundamentally identical. “There are just a few chromosomal rearrangements that have changed the way genetic material is assembled,” said Texas A&M scientist Dr. David Busbee.

4. Slugs (70%)

Eh yes ! As true as this mollusc is unsavory: we share 70% of our DNA with slugs. I know you’re dumbfounded, but when you think about it… Slugs have lungs (I swear to you), they have eyes, which they use for the same purpose as us, a brain that works according to the same chemical principles and electrochemical than ours, they have a stomach, kidneys… We are a bit like couz! So if you want to drool with impunity, drool, good people.

Note: 70% is also the percentage of genes that we have in common with sea urchins!

5. Fruit flies (61%)

Right now, that doesn’t speak to you, but what if I tell you “drosophila”? Does it remind you of anything? BINGO: your SVT courses (“organic”, for the oldest among us) at college. If we had to make these poor little creatures miserable, it’s because we actually have a lot in common in our DNA, for different biological processes involved in growth and development, in particular.

6. Chickens (60%)

I know what you say to yourself: “and my uc, is it chicken?” So I don’t have the answer to that specific question, but I can tell you that it was the International Chicken Genome Sequencing Consortium that found that even though a chicken doesn’t have as much DNA as a human has about the same amount of genes. Genes that bear similarities to ours in basic cellular structures and how they function. That’s it, so before stealing my feathers and starting a nasty pout, thank you for inquiring, in fact.

7. Bananas (60%)

No, no, I’m not fucking you! Well I say 60%, but not all scientists agree on that. For some, the similarities are more around 50%… Which is still huge, right? At least half of our DNA would be similar to that of the banana. Above all, we share various “housekeeping” genes, necessary for basic cellular function such as DNA replication or cell division.

#CheckNewsThis figure is very popular but it is based on confusion about the notions of DNA, genes and genetic proximity.

8. Apples (40%)

Fruit salad, pretty pretty, pretty. Still in the fruit section: we share about 40% similarities with apples. Phew, right? I find that ugly.

9. Daffodils (35%)

It’s surprising, but in the end… Not so much! When you think about it: the cellular mechanisms of man and that of plants have several points in common. What brings us so close to the daffodil are our cells, all made up of a membrane, a nucleus and mitochondria.

10. Yeast (about 26%)

At first glance, man and this unicellular fungus are very different. Yet… We have several similar genes. Even crazier: if we replace some of the yeast genes with equivalent genes in humans: nothing changes! Really a great medical development to be able to save yeasts in distress.
